Okay probably a stupid question. i have a 3" catless slp dp. if i were to get lets say ssac or pacesetter headers.. would these two go together? ive never seen the headers except in pictures and outside of the car they look like they extend farther than the manifold did which would mean to far out to properly connect to a dp. but alot of pictures looks like they come with a sort of dp? so im confused could someone with more modding experience explain please?
